Green teleport
The green teleport is a tile introduced in Chip's Challenge 2. They send movable objects to another green teleport chosen pseudorandomly in a direction chosen pseudorandomly.
If the exit teleport's chosen exit direction is blocked, it will try another direction. If the exit teleport is completely blocked (destination has an object on it or is blocked on all sides), the attempt to teleport immediately fails without searching for another exit teleport, and whatever was trying to enter the green teleport instead slides past it.
